Background technology
Water is one of indispensable valuable source in people's daily life, and every household has water meter record water consumption monthly.So, copy one of water meter important process becoming Running-water Company.For most of Running-water Company, it is all the management relying on manual metering to carry out using water and charge.This is not only the huge work of a workload, and there is all managerial drawbacks, as not in place, the mileometer adjustment privately of checking meter, human feelings are checked meter, privately revised water consumption etc., estimate according to the investigation of certain Running-water Company, the water loss caused because checking meter and managing improperly is about 200,000 tons/year.
For above-mentioned all drawbacks, someone proposes the solution of automatic coppying meter.Along with the development of machine vision and image processing techniques, water meter automatic data logging is made to become possibility.Take the index dial image of water meter by digital camera head and defeated people in computing machine, through computer recognizing, the reading of water meter is converted into the numeral of textual form, this not only facilitates storage and the analysis of reading, can also error rate be reduced, save manpower, raise the efficiency, achieve automatic coppying meter, facilitate condition for follow-up work provides.
Summary of the invention
The purpose of this utility model is to solve above-mentioned Problems existing, and spy provides a kind of print wheel meter reading control system for identifying.
The utility model provides a kind of print wheel meter reading control system for identifying, it is characterized in that: described print wheel meter reading control system for identifying comprises print wheel water meter 1, imageing sensor 2, Video Decoder 3, human-machine interface module 4, microprocessor 5, wireless transport module 6, wireless receiver 7; Wherein: print wheel water meter 1 is connected with wireless transport module 6 by imageing sensor 2, Video Decoder 3, microprocessor 5 successively, and microprocessor 5 is connected with human-machine interface module 4, wireless transport module 6 and wireless receiver 7 are bi-directionally connected.
Further, described imageing sensor 2 function is that the light signal of image is converted into electric signal, and described imageing sensor 2 comprises CMOS camera and visible filter.
Further, described Video Decoder 3 adopts I with described microprocessor 5
2c bus connects.
Further, described Video Decoder 3 adopts the SAA7113H video decoding chip of Philips company.
Further, described human-machine interface module 4 comprises LCD liquid crystal display and 3 × 4 keyboards.

Advantage of the present utility model: print wheel meter reading control system for identifying described in the utility model can realize Recognition of Reading, data-transformation facility to water meter, this control system reading and transmission speed are fast, working stability, accurately can identify the reading of water meter.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is a kind of print wheel meter reading control system for identifying theory structure schematic diagram.
Embodiment
The utility model provides a kind of print wheel meter reading control system for identifying, it is characterized in that: described print wheel meter reading control system for identifying comprises print wheel water meter 1, imageing sensor 2, Video Decoder 3, human-machine interface module 4, microprocessor 5, wireless transport module 6, wireless receiver 7; Wherein: print wheel water meter 1 is connected with wireless transport module 6 by imageing sensor 2, Video Decoder 3, microprocessor 5 successively, and microprocessor 5 is connected with human-machine interface module 4, wireless transport module 6 and wireless receiver 7 are bi-directionally connected.
Further, described imageing sensor 2 function is that the light signal of image is converted into electric signal, and described imageing sensor 2 comprises CMOS camera and visible filter.
Further, described Video Decoder 3 adopts I with described microprocessor 5
2c bus connects.
Further, described Video Decoder 3 adopts the SAA7113H video decoding chip of Philips company.
Further, described human-machine interface module 4 comprises LCD liquid crystal display and 3 × 4 keyboards.
Further, described wireless transport module 6 adopts 3G wireless telecommunications with described wireless receiver 7.
Further, described wireless receiver 7 is palm PC.
The main working process of print wheel meter reading control system for identifying is that imageing sensor converts this for print wheel meter reading light signal the electric signal of simulation to, the collection of water meter dial plate image is that the image information simultaneously coordinating visible filter to make to collect is more accurate by utilizing simulation camera.Due to camera output is analog video image, and must carry out a pre-service before carrying out identifying processing, this just needs Video Decoder, and the video image of simulation is converted to digital signal by it.The utility model mainly adopts the SAA7113H chip of Philips company, its SAA7113H can detect that field frequency signal is the vision signal of 50HZ and 60HZ automatically, and automatically can switch between PAL and NTSC two kinds of video formats, brightness and colourity process can be carried out to vision signal, can comparatively perfectly coordinate with selected camera.Video decoding chip passes through I
2after C bus initialization, the result of being carried out identifying processing and identification by the digital signal of microprocessor to conversion carries out wireless transmission, LCD liquid crystal display eventually through human-machine interface module shows, and information is passed in palm PC by 3G radio communication by reading, complete automatic coppying meter function.
